I am currently taking Orthocept and I usually have my period regularly every month. This past week my period lasted 3 days, was heavy and then just stopped, no spotting or anything. I have been on many different medications, including Amoxicillin for 2 weeks last month. I also have withdrawal side effects from Cymbalta and my doctor switched me to Ambien for insomnia. It is now a week after my period started and I feel lethargic even with more than a nights sleep each day. My stomach feels full and crampy which isn't normal for me after my period. With all of the possible side effects from other causes is it possible that I'm pregnant, and how can I tell this early?View Thread
